For enhanced safety, the front and rear seat shoulder belts of the Lexus NX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Nissan Murano doesn’t offer pretensioners for its rear seat belts.
With its standard Pre-Collision System with Pedestrian Detection, the Lexus NX is better at preventing collisions with pedestrians than the Nissan Murano, according to the Insurance Institute for Highway Safety:

When descending a steep, off-road slope, the NX’s standard Downhill Assist Control allows you to creep down safely. The Murano doesn’t offer Downhill Assist Control.
Both the NX and Murano have rear cross-traffic warning, but the NX offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Murano’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the NX and the Murano have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Lexus NX is much safer than the Murano:

The Lexus NX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Murano is not a “Top Safety Pick” for 2024.
